If y is the dependent variable and is the independent variable. And if the sum of the cross product of the deviations is Σ(x - x)(y-7)= -53, and also if 3.49 and 2.55 are the standard deviations for the independent and dependent variables, respectively, and we have a sample size of 20, what is the correlation coefficient between X and y? Note: 1- Do not round intermediate numbers. 2- Round your final answer to 2 decimal places. Your Answer: -0.31
